CHL8266 - CHiL Semiconductor

CHL8266 DIGITAL MULTI-PHASE GPU BUCK CONTROLLER

The CHL8266 is a 6-phase digital synchronous buck controller for regulation of high-performance GPU platforms. The CHL8266 output VID table is fully compliant with VR11.1 specifications. The CHL8266 deploys a number of efficiency shaping features. PSI can be programmed to be up to four phases for optimum light-load efficiency, and the controller can autonomo.
